If ava walks 2.75 miles per hour for 2 hours and her brother jayden runs at 7 miles per hour for .75 hour who has covered more distance

2.75*2=5.5 (Ava)
7*0.75=5.25 (Jayden)

5.5>5.25

Ava has covered more distance

2.75 * 2 = 5.5 miles Ava has walked in 2 hours. 

7 * 0.75 = 5.25 * 2.666666667 = 14 miles Jayden has ran for 2 hours. 

Jayden has covered the most distance than Ava. 

Hope this helps!

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept
